Fig. 61: Check mortar pressure
DANGER! Excess pressure on the machine!
When opening machine components these components can
unexpectedly fly open and seriously injure the operator.
Only open the machine if the pressure has dropped to 0.
1. On the mortar pressure manometer (Fig. 61/1) check whether
mortar pressure has dropped to 0 bar. If necessary, dissipate
mortar pressure by opening all cocks on the sprayer.
2. Clean mortar hoses immediately
(For how to clean the mortar hose, see chapter "Cleaning"
under "Operation" in this Operating Manual).
